A casualty is the damage, destruction, or loss of property resulting from an identifiable event that is sudden, unexpected, or unusual. 1  A sudden event is one that is swift, not gradual or progressive. 2  An unexpected event is one that is ordinarily unanticipated and unintended.
exists and is an alternate of . The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point onwards. The notation is shorter to write and makes it easier to identify elements.
Noble Gas Notation. Uses the symbol for the previous noble gas and then adds the additional electron configuration notation for the series of elements up to the next noble gas. For example, the electron notation of carbon is 1s22s22p2, and the noble gas notation is [He]2s22p2. This notation makes it easier to identify elements, and is shorter than writing out the full notation of atomic orbitals.
